What does the fortune-telling crown mean?

How to annotate the eight-character moon column with seven kills and crown belt? Thank you teacher!

Hello, the crown belt ranks third among the twelve immortals. The encounter between the seven kills of the eight-character moon column and the crown belt means that the seven kills of a person's eight-character sun stem just appear in the sky stem of the moon column, and the seven kills of the moon column are the crown belt position of the twelfth birthday. For example: Chen Jia Moon Column, Wuzi Sun Column. On may day, a is the seventh kill, which just appears in the middle of the month, and the sitting day of a is the crown of may day. thank you
